Hi, Just wondering why there isn’t a rotate function for rectangles e.g. Phaser.Geom.Triangle.Rotate. I’m trying to emulate this steering tutorial I found, but I can’t seem to find a rotate for rectangles. I’m not the best at math, so bare with me. ---

I might be missing the point of the question but… Arcade physics doesn’t have rotation. Matter JS (and I believe Impact) do. You can set `.rotation` (radians), or `.angle` (degrees) ---

Apart from what quasipickle said, Rectangle shapes are axis-aligned, which means they can’t be rotated. How you’d rotate a rectangle depends on how your code uses it. As a side note, I don’t think Impact can rotate bodies. Only MatterJS supports complex collision. ---

Hi, I wasn’t thinking of using a rectangle for collisions/overlays per se, but I guess thinking about your replies that’s what it is. I was just thinking of a rectangle that is projected in front of my enemy ship and can rotate along with it. Kind of like the example below, but with a rectangle. > **[Phaser - Examples - Contains](https://phaser.io/examples/v3/view/geom/triangle/contains)** > > Desktop and Mobile HTML5 game framework. A fast, free and fun open source framework for Canvas and WebGL powered browser games. I’m trying to model some ideas from [http://opensteer.sourceforge.net/](http://opensteer.sourceforge.net/) where each ship has a long rectangular box that helps it steer away from obstacles and other ships. I’ll check into Impact and Matter JS, but I’ve been working on this game for a long time and would like to release it. Thanks for the help, DaSoup ---

Think I’ll try two triangles and see how it works. ---

Some other ideas if two triangles does not work for you and you don’t want to use matter/impact. 1: Perhaps create a rectangle using the factory? This will make a gameobject that is like the geom rectangle but can be rotated. this.add.rectangle(…) to create it and then move/rotate it with relation to the ship gameobject and set visible false if the rectangle is not meant to be seen. 2: You can get the points of a Phaser.Geom.Rectangle (or change to Phaser.Geom.Polygon) and then loop through them to update their position using Phaser.Math.RotateAround(…) again using the ship gameobject as a point to rotate around/with. ---

I’ll look into those. Thanks. Seems like every door I open in Phaser leads to like five more. I appreciate the help.
